MOLD FOR LINE-CASTING- MACHINES.

Specification of Letters Patent.

Patented May 8, 1917.

Application filed June 4, 1913. Serial No. 771,766.

To all whom it may concern:

Be it known that I, TI-IOMAs' S. HOMANS, a citizen of the United States,residing at Hempstead, in the county of Nassau and State of New York,have invented new and useful Improvements in Molds for Line- CastingMachines, of which the following is a specification.

This invention relates to improvements in line casting machines, andmore especially to those of the linotype class which employ a moldwheelcarrying molds each composed of a mold body, a cap, and linersinterposed between the body and cap and forming therewith a cavity inwhich the slug is cast. The primary object of the present invention isto provide improved means for holding together the mold body and cap,such means being adjustable to enable liners of different thicknesses tobe accommodated between the body and cap.

To this end, the invention consists in certain improvements, andcombinations and arrangements of parts, all as will be hereinafter morefully described, the novel features being pointed out particularly inthe claims at the end of the specification.

In the accompanying drawing Figure 1 is a front elevation of a portionof a mold wheel and a mold mounted thereon, the mold being constructedin accordance with the present invention;

Fig. 2 represents a vertical section through the left-hand end of themold as shown in Fig. l, the parts being on an enlarged scale;

Fig. 3 is a detail perspective view of one of the improved clamps orconnecting devices;

Fig. 4. is a perspective View of the left hand end of the mold andshowing the mode of operation of the improved clamp or connectingdevice.

Similar parts are designated by the same reference characters in theseveral views.

The invention in the present instance is shown in connection with a moldof the type employed generally in line casting machines of the linotypeclass, and the invention will be so described in the specifica tion,although it is to be understood that the invention is not restricted tothe particular construction shown, as equivalent constructions may beused within the scope of the claims at the end of this specification.

In the accompanying drawing, 1 represents a portion of the mold wheel ordisk as used generally in machines of the linotype class, this wheel ordisk being movable to carry the mold to and from the line of matricesfrom which a cast is tobe made, and such wheel or disk is also rotatableto bring the mold containing the cast slug to the ejecting position.Rotation of the mold toeffect the latter operation is usually producedby power mechanism including a pinion which cooperates with the gearteeth 2 formed on the rim or periphery of the mold wheel. The mold wheelor disk is provided with a suitable number of slots 3, each adapted toaccommodate a mold. Each mold is composed of a mold body 4:, a mold cap5, and liners 6 and 7. The mold body and cap define the top and bottomof the mold cavity M, while the liners 6 and 7 determine the height ofthis cavity and define the ends thereof. It is customary to employ anumber of liners of different thicknesses to enable the casting of slugsof different thicknesses,'and the length of the line or slug to be castis gaged by the length of the lefthand liner 6. The mold body f isformed with ledges or keepers 8 to cooperate with the lugs on the lowercorners of the matrices, thereby alining them properly before the mold,and this mold body is secured in fixed position on the mold wheel by thescrews 9. Various means may be devised for holding the mold cap to thebody of the mold. A common way is to hold the mold cap in position byscrews passing through the rim of the mold wheel or disk, but sucharrangements have proven objectionable for the reason that the rim ofthe mold wheel is light and is often broken by the strain imposedthereon by tightening of the mold cap screws. Also, bolts have been-usedwhich passed through the liners, but such arrangements are alsoobjectionable for the reason that removal of the bolts is necessarybefore the liner can be removed from the mold. The present inventionprovides a simple and convenient means for connecting the mold cap andbody and which obviates the objections incident to the use of otherdevices heretofore proposed and used for such purpose. As shown in thedrawing, a pair of clamping or connecting members 10 are hinged to theopposite ends of the mold cap 5 by the pivot pins 11, these membersbeing formed at their lower ends with lugs or shoulders 12 which projectforwardly. The mold body is provided at its opposite ends with screws 13which, when the clamping or connecting members 10 are swung intooperative position, will occupy positions to cooperate with theforwardly-projecting lugs or shoulders 12. These screws 13 arepreferably inclined in order to facilitate the application of ascrew-driver thereto to turn the screws either in a direction to apply adownward pressure on the members 10, thereby drawing the mold cap downfirmly uponthe liners resting on the top of the mold body, or to loosenthe screws and thereby permit the connecting members to be swungoutwardly beyond the ends of the mold and enable the mold cap to beremoved by sliding it forwardly with respect to the mold wheel. The moldbody is formed at each end with a slot 14 to enable the respectiveconnecting member 10 to swing into operative position, and each liner isalso formed at its end with a slot 15 which accommodates the respectiveconnecting member 10 when the latter assumes an operative position. Thewalls of the slot 15 in each liner may, if desired, be fitted closely tothe corresponding surfaces of the respective member 10 whereby thelatter will serve to position the liner in a face-wise direction, orthese liners may be positioned, as usual, by dowels 16.

The present invention provides means which is independent of the rim ofthemold wheel for connecting and securing together the mold cap andbody, and it enables the mold to be opened and liners of difi'erentlengths or thicknesses to be inserted and then secured, with facility,as it is only necessary when it is desired to change a pair of liners toloosen the screws 13, thereby freeing the connecting or clamping members10 and swinging these connecting members outwardly into a horizontalposition, the mold cap being then free to be removed and the liners maybe then changed. After the liners have been changed, the members 10 areswung downwardly, bringing the lugs or shoulders 12 thereon beneath therespective screws 13 and the latter are then tightened to secure themold cap and liners in position. The screws 13 constitute adjustablemeans for accommodating liners of difierent thicknesses between the moldbody and cap.

I claim as my invention 1. In a mold of the class described, thecombination of a mold having relatively separable parts to form the topand bottom walls of the mold cavity, and means for holding together themold parts comprising a clamp member attached to one of the mold partsand having an offset lug within the plane of the mold, and an adjustablemember on the other mold part cooperative with said lug to exertpressure to hold the mold cap and body together.

2. In a slug-casting mold for machines of the class described, thecombination of the mold body, the mold cap, clamp members pivotallyattached to one of said mold parts to swing toward and from therespective ends of the mold and provided with shoulders, and adjustabledevices on the other mold part arranged to act on said shoulders to drawthe cap and body relatively toward one another.

3. In a line casting mold, the combination of the body portion, the capportion, the

interposed liners, clamp members pivotally connected to the cap andextending into the body portion and having steps or shoulders offset tooccupy positions in the plane of the mold, and pressure devices on thebody adapted to act on said steps whereby the body and ca may be held tothe liners.

4. In com ination in a line casting mold, the body, the superposed cap,the liners interposed between said cap and body, connections extendingfrom the cap down to the body and provided with forwardly offset steps,and downwardly-acting screws in the body adapted to engage theconnections and thereby hold down the cap.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
